Detailed implementation manners

[0018] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model.

[0019] This application provides a clamping device for component processing, which is mainly used to solve the problem that when polishing the surface of a tubular component, it is necessary to rotate the tubular component to cooperate with the polishing. Therefore, the general operation method is to clamp one end of the component and then rotate the component. At present, during the process of rotating a longer tubular component, the other end of the component is often unstable under the action of gravity, which is likely to affect the polishing effect, and the following technical solutions are provided. The following will be combined with Figures 1-4 be described in detail:

[0020] A clamping device for component processing, comprising: a base 1 with two symmetrically arranged chucks 2 above. After the user installs the base 1 inside a processing device such as a polishing machine through a number of mounting bolts 13, and then sleeks a component on the surface of the chucks 2, by controlling the distance between the two chucks 2 through an adjustment mechanism 3, and making the two chucks 2 abut against the inner wall of the component, the limitation of the component on the surfaces of the two chucks 2 can be achieved. Then, while driving the two chucks 2 to rotate through a driving mechanism 4, the positions of the two chucks 2 along the length direction of the base 1 are adjusted, and the surface of the component can be processed in cooperation with a processing device such as a polishing machine. A notch 5 is formed on the surface of the base 1, and it further comprises two torsion springs 6. Two adjusting rods 7 are rotatably installed on the inner wall of the notch 5 through the two torsion springs 6. At the same time, a pressing rod 8 is arranged between the two adjusting rods 7. Two protrusions 9 are fixedly installed on the inner wall of the notch 5. The pressing rod 8 is arranged between the two protrusions 9, enabling the pressing rod 8 to slide between the two protrusions 9. Two abutting blocks 10 are fixedly installed on both sides of the pressing rod 8. Smooth surfaces 11 are formed on the surfaces of the two abutting blocks 10, and one end of each of the two adjusting rods 7 abuts against the surfaces of the two smooth surfaces 11 respectively. It further comprises a force-applying mechanism 12, and the force-applying mechanism 12 is used to apply a force to keep the pressing rod 8 in place. Therefore, when the user presses the component against the surfaces of the two adjusting rods 7 and the pressing rod 8, the pressing rod 8 and the two adjusting rods 7 can be driven to move simultaneously. Under the action of the two torsion springs 6 and the force-applying mechanism 12, the two adjusting rods 7 and the pressing rod 8 can achieve flexible support for the component. The main components of the adjustment mechanism 3 are: a double-headed electric push rod 302 with both ends fixedly installed on the surfaces of the two chucks 2 respectively, and an installation bin 301 is fixedly sleeved on the surface of the double-headed electric push rod 302. When the user drives the two ends of the double-headed electric push rod 302 to expand and contract, the two chucks 2 can be driven to move simultaneously. The main components of the driving mechanism 4 are: a first motor 402 fixedly installed on the surface of the base 1. At the same time, a driving threaded rod 401 is threadedly inserted into the inner wall of the base 1, and a driving block 403 is threadedly sleeved on the surface of the driving threaded rod 401. When the user drives the output end of the first motor 402 to rotate, the driving threaded rod 401 fixedly installed with the output end of the first motor 402 can be driven to rotate, thereby driving the driving block 403 to move along the length direction of the base 1. A lifting groove is formed on the surface of the driving block 403, and a lifting electric push rod 404 is fixedly penetrated through the inner wall of the lifting groove. By controlling the expansion and contraction of the lifting electric push rod 404, the user can drive an installation plate 405 fixedly installed at one end of the lifting electric push rod 404 to lift. And a second motor 406 is fixedly installed on the surface of the installation plate 405, and one end of the installation bin 301 is rotatably inserted into the surface of the installation plate 405. When the user drives the output end of the second motor 406 to rotate, the installation bin 301 fixedly installed with the output end of the second motor 406 can be driven to rotate, thereby realizing the vibration of the two chucks 2.The installation method of two torsion springs 6 is as follows: two fixing rods 14 are both fixedly installed on the inner wall of the notch 5, and the two torsion springs 6 are respectively sleeved on the surfaces of the two fixing rods 14 in a sliding manner. The two torsion springs 6 are fixedly installed on the inner wall of the notch 5 and the other ends are respectively fixedly installed on the surfaces of the two adjusting rods 7. When the blocking component abuts against one end of the two adjusting rods 7, under the action of the two torsion springs 6, the two adjusting rods 7 will be subjected to a force to return to their original positions. The main components of the force application mechanism 12 are: a force application plate 1202 fixedly installed at one end of the pressure rod 8, and two force application frames 1201 are fixedly installed on the inner wall of the notch 5. The two ends of the force application plate 1202 are respectively inserted into the inner walls of the two force application frames 1201 in a sliding manner and two springs 1203 are fixedly installed on the surface. The other ends of the two springs 1203 are respectively fixedly installed on the inner walls of the two force application frames 1201. Therefore, when the pressure rod 8 is pressed down, it will drive the force application plate 1202 to slide in the inner walls of the two force application frames 1201, thereby compressing the two springs 1203 and applying a force to the pressure plate to bounce back to its original position.,

[0021] During use, after the user installs the device on the internal part of a processing device such as a polishing machine through a plurality of mounting bolts 13 on the base 1, the component is placed on the surfaces of the two adjusting rods 7 and the pressure rod 8 and then pressed down, so that the pressure rod 8 can be pressed down, driving the two abutting blocks 10 to slide on the inner wall of the notch 5. During this process, one end of the two adjusting rods 7 slides on the sliding surfaces 11 on the surfaces of the two abutting blocks 10, thereby realizing the clamping of one end of the component through the two adjusting rods 7 and the pressure rod 8. Then, the other end of the component is sleeved on the surfaces of the two chucks 2, and the distance between the two chucks 2 is controlled by the adjusting mechanism 3 to abut against the inner wall of the component. While driving the two chucks 2 to rotate through the driving mechanism 4, the positions of the two chucks 2 along the length direction of the base 1 are adjusted, and the surface of the component can be processed in cooperation with a processing device such as a polishing machine. With such a setting, during the processing process, the two torsion springs 6 and the force application mechanism 12 can drive the two adjusting rods 7 and the pressure rod 8 to abut and clamp the surface of the component, ensuring the stability during the processing process and fully reflecting the practicability of the device.

[0022] As Figure 1 shown, in some embodiments, to further optimize the solution, abutting wheels 15 are rotatably installed at both ends of the two adjusting rods 7 and one end of the pressure rod 8. During use, the component abuts against the surfaces of a plurality of abutting wheels 15, and at the same time, when the component rotates, the two abutting wheels 15 will also rotate simultaneously, further ensuring the surface of the component.

Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present utility model.
